SPECIFICATION forming part of Letters Patent No. 349,599, dated September 21, 1886.

Application iilcd October 27, 1885. Serial No. 181,092. i (NoY model.) l

T LZZ whom it may concern: Be it known that l, FRANK H. MARKER, a citizen of the United States, residing at Elkhart', in the county of Elkhart and State of Indiana, have invented a new and 'useful Improvement in Lamp Trimming and 'Extinguishing Attachments, oi' which the following is a specification, reference being had to the accompanying drawings. Y Io- This invention relates tolamp-burners; and it has for its object to provide an attachment vfor the same, which will serve to extinguish the light and trim the wick at the same time. The design of the present invention resides, 1.5 more particularly,- in certain improvements on the construction shown in Letters Patent No. 321,989, granted to me July 14, 1885. y

The invention consists in certain details of construction and novel combination of parts, 2o as will be hereinafter set forth, and particularly specified in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a lamp-burner with my improvement applied thereto, the hinged cap of the burner being thrown back to expose the wick-tube and the proximate parts. 2 is a transverse vertical section through the wick-tube with the cap closed down, the attachment being shown in dotted lines in the 3o position assumed when extinguishing the light and trimming the wick. Fig. 3 isv al detail perspective view of my attachment detached from the wick-tube. Fig. 4 is an elevation of the front side of my attachment. Fig. 5 is a detail perspective view of the operating-rod, showing the bladeheld rigidly by rivets to the same.

Like letters are used to indicate corresponding parts in the several iigures.

y 4o Referring to the drawings, A designates a lamp-burner of the ordinary construction, a description of which would appear to be unnecessary for a full understanding of the present improvement.

, In applying my attachment, a plate, B, is

secured by solder or otherwise over A, the perforated diaphragm of the burner, on one side of the wick-tube C, and is providedwith curved arms D on each side, which extend 5o upward and are soldered to the opposite up- Fig.

per ends ofthe wick-tube. Eyes c are provided on the plate B at its inner cdge,yadja cent to thewick-tube.

E designates a wire rod having the main longitudinalarm a journaled in the eyes ct of the plate B, the inclined arm b, at theouter end of the arm a, passing through a slot, c, of the diaphragm A', and having its lower end turned outward, as at c, to provide an operating-handle. At the inner endv of the A main 6o arm a the wire rod is bent outward and slightly upward a short distance, as at'cl, in a direction at right angles to the main arm, and then longitudinally, asatf, to provide a pintle on which the extinguishing and trimming blade 55 is pivoted. Said blade F is shaped substantially like a hoe-blade in cross-section, its lower or front edge being sharpened. The rear or upper edge is provided with eyes g, through which the arm f of the rod E is 7o passed. Between the eyes the blade is cut out and pressed upward, as at h, to i'orm an extension, for the purpose presently described. A spring, G, is coiled on the main arm a., between'the eyes a of the plate B, one end of 75 the spring being secured to the plate and the other end extending outward or upward until it reaches the arm f, around which it is .coiled between the eyes g of the blade F,

the other end of the spring being secured toSo theextension z. By this arrangement ot' the spring G it is caused to press the exension h upward and force the blade downward ontothe upper edge of the wick-tube; and it alsoimparts aspring action to the wire S5 rod E, so as to retain the parts normally out of engagement with the wick-tube. The blade F is set at an incline, its outer sharpened edge being lowerthan the point of connection with the operating-rod on its pivotal point, and in 9o this manner the sharpened edge only of the blade acts upon the upper edge of the wicktube. The curved arms D serve to guide the blade in its movements, the spring G retailiing the sharpened edge of the blade normally in engagementwith,tlieupper edge of the arms D. Since the upper ends ofthe said arms come flush with the upper edge'of the wick-tube, the working ofthe blade over the arms will serve to keep it in a proper position, so that it roo will sweep over the entire upper edge of the wick-tube, clear the accumulation of matter therefrom, and push it over to the opposite side of the wick-tube.

The operation of my invention is as follows: The springy G serves to retain the parts normally in the position shown in Fig. 1, the eX- tension h of the blade resting on the diaphragm A of the burner, while the sharpened front edge ofthe blade is held at all times against the upper edge of the arms D by the action of the spring G. The inclined arm b is also held against the lower edge of the burner by the action of the spring. By pressing against or swinging the end e of the rod E the main arm a is rotated, causing the winding of the coils of the spring thereon, and also causing the blade F to work over the arms D, and transversely across the upper edge of the wick-tube. By the working of the blade over the upper edge of the wicktube the light is caused to be extinguished, and the hard crust which always remains on the upper edge ofthe wick is severed; and as the blade sweeps entirely across and beyond the wick-tube the severed portion of the wick is carried over by the blade yto the opposite side of the wick-tube. As soon as the hand of the operator is released from the end e of the rod E the spring G reacts and causes the blade F and the rod to berestored to their normal position.

It will be observed that the action of the extinguishing and trimming attachment is decidedly more positive than the spring-pressed cap or cover described and claimed in my aforesaid patent. The trimming ofthe wick and extinguishing of the iiame do not depend upon the uncertainties of a spring action, such as follows from the use of a spring-pressed cap or cover. rIhe movement and operation of the blade are communicated directly from the hand of the operator, the spring employed being used merely to retain the blade in engagement with the arms D, and also to restore the parts to their normal positions after the operation has been completed.

I have shown the blade F as pivoted ou the arm f of the rod E, and provided with a spring to retain the blade at an incline,l with its front edge resting on the arms D. In place of this arrangement I may dispense with the spring, pressed pivotal attachment of the blade and secure it rigidly on the arm f, care being taken to have the blade set normally, and at all times on an incline and in engagement with the upper edges of the arms D. Of course when this arrangement is adopted it will not be necessary to employ the curved guide-arms D, and they are therefore dispensed with, and a spring should still be employed to restore the operating-rod E with the blade to a normal position; but the spring should not connect with the blade at all, it acting only on the rod E, which, being fixed with the blade, will cause the latter to follow the movement of the rod. However, I prefer the construction shown, as it enables the parts to be more number of parts necessary to constitute an attachment, changing the mode of operation so as to insure a more positive action, and making such additional improvements as the test of practical use had found it necessary to employ.

It will be observed from the foregoing description, taken in connection with the drawings, that the blade is arranged on one side of the wick-tube of the burner, and that it is normally held depressed below the plane of the upper edge thereof, so that it will not interfere with the light when thelamp is in use, and will not be in the way of the hinged cap of the burner in operating the latter.

Changes in the forni and construction of parts may be resorted to without departing from the spirit or scope of my invention.

It will be understood that in the present arrangement I employ the positive action of the hand of the operator to work the blade, and a spring to return the same after the operator has completed the necessary mvement. Since the loperation of the blade is against the pressure of the spring, it will be observed that sufficient force will be given to the blade to insure a positive cutting action, which will cause the wick to be trimmed more eifectually than heretofore.
